Title: Guralp Affinity Evaluation for SNL Infrasound Testbed.

Abstract

Sandia National Laboratories has tested and evaluated a new digitizer, the Affinity, manufactured by Guralp Systems. This digitizer is used to record sensor output for seismic and infrasound monitoring applications. The purpose of the digitizer evaluation was to measure the performance characteristics in such areas as sensitivity, self-noise, dynamic range, system noise, relative transfer function, analog bandwidth, harmonic distortion, common mode, cross talk, timing tag accuracy and timing drift. The Affinity provides eight, rather the typical six, channels of 24 bit high sample rate digitization. Moreover, it also provides 16 single-ended, 24 bit resolution, low sample rate auxiliary channels. The Affinity digitizer is undergoing these tests prior to installation in the FACT site infrasound test bed.
